Our team will be evaluating NitroKey Pros as devices to replace yubikeys (https://www.nitrokey.com/) and I will follow up here with the results and general recommendations once our testing is complete.

If you are already using yubikeys, there is no need to replace them, as this will not result in a net improvement in security -- especially if you are only using them for one-time password functionality (press the button to emit a 6-digit code). If you are looking to get a device for storing your private PGP keys, I recommend against using Yubikey 4 devices -- but NEOs are okay, as they still use open-source code.

I strongly believe that all security devices must be powered by libre software and I am saddened at the steps taken by Yubico to make yubikey 4 a black-box platform.

Ballintoy Harbour is a nice little harbour on Irelands northern coast. When we tried to go there for the first time, we couldn't even get nearby and take a look from the distance. We've been stopped by a security officer and all he said was "They're filming", expecting that the rest of the story was clear to us. But sorry, nope. So, maybe we were the first people who came by that day who asked for more information. "Game of thrones!" was the brief answer. Ok!

Luckily we planned to stay some more days in Northern Ireland, so we could get there on our last day before continuing our road trip along the coast. I took this wonderful picture while the film crew put away the last kilometers of cables behind me.

A TV series playing at this wonderful scenery... I think I should give it a try :-)

It is done – since a few minutes ago the Ancient Warehouse District in Hamburg has officially been pronounced world cultural heritage. This means the Wunderland is also a piece of this world cultural heritage, at least the face of our building is ;-)

We have been anticipating this for weeks now, and therefore have prepared a little film of congratulation. Hundreds of emails and telephone calls have contributed to this video. And here it is. The world welcomes the Ancient Warehouse District and the best wishes come from other places pronounced world cultural heritage. We are proud to now be one of you.

We would like to take this moment to say thank you to all the contributors of the video. THANKYOUTHANKYOUTHANKYOU – it's so great that you have made this possible!!!
